Mouth stretches into, and end is placed in the top of distributing device, and material flows into distributing device by charging pipe end.This feeding manner is easy to cause liquid
Body is unevenly distributed in distributing device, causes local hydrops phenomenon, is unfavorable for forming uniform initial liquid film, is reduced the separation of equipment
Efficiency and product quality.
Invention content
To overcome drawbacks described above, the technical problem to be solved in the invention：There is provided a kind of scraped film type short-path distillation initially into
Expect device, the invention is simple in structure, reasonable design.Initial charge device, first liquids are added above original device distributing device
Material flows into loading hopper by feed pipe, and then the annulus between loading hopper and rotary shaft is flowed into distributing device, realizes
Central feeding so as to which the uniformity of cloth be effectively ensured, improves distillation efficiency.
To solve the technical problem, the technical measures that the present invention is taken：A kind of scraped film type short-path distillation initial charge
Device, including pivot flange, fixed baffle ring, floor, loading hopper；Further, bolt hole is provided on above-mentioned pivot flange, thereon
Seal groove is provided in lower both ends of the surface；
Further, the bottom surface of above-mentioned pivot flange is welded with fixed baffle ring, the internal face of fixed baffle ring and pivot flange it is interior
Wall surface is on same periphery；
Further, 3 pieces of identical floors are welded on the base circumference of above-mentioned fixed baffle ring, the interval between adjacent two floor
Angle is 120 °, and the bottom end of floor and the top edge welding of loading hopper are, it can be achieved that support the fixed of loading hopper；
Further, the outside wall surface of above-mentioned fixed baffle ring is close to evaporate the internal face of cylinder, when the feed arrangement is packed into molecule
When in distiller, loading hopper is inserted in rotary shaft by intermediate round charging hole, can enable feed arrangement radial constraint,
Ensure the stability and assembly precision of feed arrangement；
Further, above-mentioned loading hopper with rotary shaft is concentric installs, the vertical axis both ensured coincides, charging hole with
Uniform annular slot is formed between rotary shaft；
Further, above-mentioned pivot flange is located between two flanges of evaporation cylinder upper end, passes through bolt and sealing ring and cylinder
Body airtight connection.
Compared with prior art, advantages of the present invention is：With feed tube, liquid material is fallen to be leaked in feed arrangement
It struggles against on inner conical surface, distributing device is flowed by the annulus between loading hopper and rotary shaft, central feeding is realized, avoids cloth
The generation of uneven, the local hydrops phenomenon of material is conducive to improve the uniformity of initial liquid film.
Description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, to embodiment or will show below
There is attached drawing needed in technology description to be briefly described.
Fig. 1 is Standard figure of the present invention；
Fig. 2 is structure top view of the present invention；
Fig. 3 is feed arrangement trimetric drawing；
Fig. 4 is the half sectional view of feed arrangement；
1st, distributing device 2, feed arrangement 2-1, loading hopper 2-2, pivot flange 2-3, upper seal groove
2-4, fixed baffle ring 2-5, bolt hole 2-6, floor 2-7, lower seal groove cavity 3, feed inlet

Specific embodiment
1st, below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out it is clear,
It is fully described by.As shown in Figure 3, Figure 4, the present invention provides a kind of scraped film type short-path distillation initial charge device, is leaked including charging
Struggle against 2-1, pivot flange 2-2, fixed baffle ring 2-4 and floor 2-6.As Figure 1 and Figure 4, it is provided with bolt hole on pivot flange 2-2
2-5 has seal groove 2-3 and lower seal groove cavity 2-7 in upper and lower ends face；The bottom surface of pivot flange 2-2 is welded with fixation
Baffle ring 2-4, the internal face of fixed baffle ring 2-4 is with the internal face of pivot flange 2-2 on same periphery；Fixed baffle ring 2-4's
It is welded with 3 pieces of identical floor 2-6 on base circumference, the interval angles between adjacent two floor are 120 °；The bottom end of floor 2-6 with
The top edge welding of loading hopper 2-1, realizes and the fixed of loading hopper is supported；When feed arrangement 2 is fitted into molecular still
When, loading hopper 2-1 is inserted in rotary shaft 6 by intermediate round charging hole, and the outside wall surface of fixed baffle ring 2-4 is close to evaporate cylinder
Internal face, can enable 2 radial constraint of feed arrangement, ensure the stability and assembly precision of feed arrangement 2；Loading hopper
2-1 and the concentric installation of rotary shaft 6, ensure that the vertical axis of the two coincides, and uniform circle is formed between charging hole and rotary shaft 6
Circumferential weld gap；Pivot flange 2-2 is located between the upper flange 4 of evaporation cylinder upper end and lower flange 5, passes through bolt hole 2-5, upper sealing
